ARTICLE VII
PROPER USE OF THE SANITARY WASTEWATER SYSTEM
Section 701 - Restricted Uses of the Sanitary Wastewater System
No storm sewer, connection, drain, downspout or arrangement which will permit surface run-off to enter the sanitary wastewater system is allowed.
Section 702 - Restricted Discharges
Where necessary in the opinion of the District Staff, any user of the District wastewater system shall provide, at his own expense, such preliminary treatment as may be necessary to reduce objectionable characteristics or constituents to within the maximum limits provided for in this article. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the District Engineer. No construction of such facilities shall be commenced until the District Engineer’s approval has been obtained in writing. The completed facilities shall not be placed in service until they have been inspected for conformance to the approved plans and the final construction approved by the District Engineer. The approval of the plans and inspection of construction shall not relieve the owner from complying with discharge limitations set fourth in this chapter.
Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in the satisfactory and effective operation by the owner at his expense.
No person shall discharge or cause to be discharged to the sanitary wastewater system any substances, materials, waters, or wastes in such quantities or concentrations as will:
1 - Create a fire or explosion hazard including, but not limited to, gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas;
2 - Cause corrosive damage or hazard to structures, equipment, or personnel of the wastewater facilities, but in no case shall discharges with pH lower than 5.0 be made unless the Operator determines the facilities can accommodate such discharges;
3 - Cause obstruction to the flow in sewers, or other interference with the operation of wastewater facilities due to accumulation of solid or viscous materials;
4 - Constitute a rate of discharge substantially above normal rates of discharge of sludge volumes, sufficient to cause interference in the operation of the sanitary wastewater system;
5 - Contain heat in amounts which will accelerate the biodegradation of wastes and thereby the formation of hydrogen sulfide in the sewer system or inhibit biological activity in the wastewater treatment facilities, but in no case heat in such quantities that the temperature at the wastewater treatment facilities influent exceeds 40 degrees centigrade (104 degrees F) unless the Operator determines the facilities can accommodate such heat;
6 - Contain more than 25 milligrams per liter of non-biodegradable oils of mineral or petroleum origin;
7 - Contain more than 100 milligrams per liter of oils, fats, or grease;
8 - Contain any noxious or malodorous gas or substance which either singly or by interaction with other wastes, is capable of creating a hazard to life, or preventing human entry into manholes for their maintenance and repair, or causing a public nuisance;
9 - Contain any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Operator in compliance with applicable State or Federal regulations;
10 - Contain any garbage that has not been properly shredded;
11 - Contain any odor or color producing substances exceeding concentration limits, which may be established by the Operator.
12 - Result in a treatment plant effluent that cannot meet the requirements of the District's permits as issued by the Department of Environmental Quality;
13 - Cause a hazard to human life, be deleterious to waste treatment structures or processes, or create a public nuisance;
14 - Contain regulated metals such as silver, lead, mercury, selenium, barium, and arsenic.
15 - Contain Federally regulated substances in quantities sufficient to cause increased treatment effort and/or impact sludge classification and disposal costs.
16 - Contain Septage (defined as a concentrated substance removed from a wastewater or any other type of holding tank, including but not limited to RV’s, septage haulers, and any discharges into a sewer lateral cleanout.)
Interceptors Required:
A property owner, or their designated representative, shall make application for a Grease Trap/Interceptor Permit to the District along with plans and specifications for review of the design, specifications, and installation.
The District is not liable in any way for any part of an interceptor or grease trap design, installation, or maintenance.
The applicant shall be responsible for notification of District requirements to all parties affected, including but not limited to the applicant’s contractors.
The applicant shall be the designated contact to the District for the entire interceptor/grease trap design and installation.
A District permit and approval by the District Engineer shall be issued prior to the start of the interceptor/grease trap installation.
Grease, oil, sand, and grit interceptors or traps shall be provided when, in the opinion of the District, they are necessary for the proper handling of wastes containing grease, or any flammable wastes, sand, grit or other harmful ingredients; except that such interceptors shall not normally be required for a building used for private living quarters or residential units. Interceptor/grease traps shall be required at all public premises where food is served, such as restaurants, cafeterias, and boarding houses. All interceptors shall be of a type and capacity approved by the District, and shall be so located as to be readily and easily accessible for cleaning and inspection. A food preparation or food handling facility with a seating capacity of up to one hundred persons shall install a grease interceptor with a minimum one thousand gallon holding capacity. Owners of facilities requiring larger interceptors or traps shall contact the District to determine the appropriate size required. All Interceptors shall provide a four-inch clean-out on the effluent side of the grease trap or grease interceptor or kitchen wastewater discharge line for sampling purposes. The owners or operators of those facilities needing to install such a device shall contact the District. All grease, oil, grit, and sand interceptors shall be maintained in a continuously maximal operational condition in accordance with the manufacturer’s instructions, at the user's expense. The user shall produce records of maintenance and/or cleaning upon request.
Businesses or private citizens utilizing chemicals containing regulated metals or substances in their process or hobbies shall install appropriate interceptors designed to prevent any discharge of the regulated metals or substances to the District sewer system.
Section 702.1 – Permit Limitations for Wastewater Discharge
Wastewater discharge from Grease traps or grease interceptors shall not exceed one hundred milligrams per liter (100 mg/L) for total suspended solids (TSS), one hundred milligrams per liter (100 mg/L) for biochemical oxygen demand (BOD) and one hundred milligrams per liter (100 mg/L) for oil and grease.
Section 702.2 - Monitoring Requirements
The District wastewater inspector may sample wastewater discharge from a grease trap grease interceptor when noncompliance with this article is suspected. If the analytical testing indicates a violation of the TSS and BOD limitation, the food preparation or food handling or grease receiving or grease treatment facilities owner shall be responsible for the cost of analytical testing and subject to payment of surcharge and fines as specified herein.
Where violations of discharge permit limitations have occurred, the frequency for additional sampling and testing shall be determined by the District Board of wastewater management.
Grease receiving or grease treatment facilities:
1 - There shall be no discharge of floating solids or visible foam in other than Trace amounts from grease receiving or treatment facilities.
2 - Samples taken in compliance with the monitoring requirements specified in this section shall be taken at the discharge point from the final treatment unit.
Section 702.3 - Reporting Requirements
All permitted food preparation or food handling facilities and grease receiving or grease treatment facilities shall submit copies of analytical tests if required as a result of current or previous discharge permit violations for wastewater discharge.
It shall be the responsibility of the owner of any food preparation of food handling facility to have a completed copy of the most recent grease trap or grease interceptor waste manifest available to the District at the time of a wastewater inspection. Failure to submit a waste manifest at time of wastewater inspection is a violation of this article.
A completed grease trap or grease interceptor waste manifest shall include the following information:
1 - Name and address of person, company or other legal entity pumping and transporting grease trap or grease interceptor waste.
2 - Number of gallons pumped from grease trap or grease interceptor.
3 - Holding capacity of pumper truck.

Section 702.4 - Surcharge for Excessive Strength Discharge
Food preparation or food handling facilities and grease receiving or grease treatment facilities that discharge excessive strength BOD and SS shall be charged a surcharge of two hundred fifty dollars per a day until such time that the strength of discharge is no longer determined to be excessive, in addition to the penalty provided in Section 209 of this Ordinance.
Section 703 - Damage to the Wastewater System
Any person who causes damage to the District’s wastewater system shall be liable to the District for all costs incurred to identify the cause and correct the damage. The definition of damage may include but is not limited to repairs, additions, spillage of sewerage, and illegal discharges. Failure to notify the District, or correct the damage, or reimburse the District for the costs incurred shall be considered in violation of this Ordinance.
Section 703.1 - Discharges to be reported: Accidental / Discharges: Tests and analyses
Every user of the District wastewater system shall immediately report to the District any accident, negligent act or other occurrence that occasions a discharge to the District wastewater system of any wastes or process waters that exceed the permissible limits for such wastes established by the District. All tests and analyses of the characteristics of waters and wastes shall be determined in accordance with the standards on file with the District.
Section 703.2 - Remedies
In addition to any criminal fine which may be imposed for violation of any provision of this section, the user shall be liable for all charges which may be assessed by the District on any user of the District wastewater system who discharges wastes containing impermissible quantities of prohibited substances into the District wastewater system. The District will assess charges based on the costs incurred by the District in surveillance, sampling and testing of the discharges, for additional operating and maintenance expenses, or for any other action required to identify, handle, process or supplement normal activities due to the unauthorized discharge of wastes, plus overhead charges.
If the discharge is a threat to the public health, safety or welfare, the District may initiate an enforcement action without giving notice.
Upon notice of the final determination by the District of an assessment or order to correct an unauthorized discharge, the responsible party shall tender the amount assessed within ten days of the date ordered and discontinue the unauthorized discharge as ordered by the District. In the event the unauthorized discharge is not corrected or the assessment is not tendered, continued operation resulting in a discharge is unlawful, and the discharge will be a public nuisance which may be adapted by order of a court of competent jurisdiction. This remedy shall be in addition to any other remedy.
Section 704 - Federal Standards
In the event that the Federal government promulgates rules or regulations applicable to the District specifying the quantities or concentrations of substances or pollutants which may be discharged by a user, that Federal regulation shall supersede the affected portions of Section 702 above.
